Abstract

A vehicle marker light assembly including a plurality of preferably serially-connected, programmable light unit modules, each module having a microcontroller and a plurality of LEDs, which have a dual function as a marker light and, alternatively, as an emergency or warning light. In a preferred embodiment, microcontrollers of adjacent modules are programmed to communicate instructions to the light unit modules, causing the LEDs to flash in one or more predetermined patterns or sequences. In this embodiment, the light unit modules are configured in longitudinal strips or other desired forms, and are designed to operate on low amounts of current. In another preferred embodiment, a controller providing command instructions to the light unit modules causes flashing of the marker lights in the predetermined patterns or sequences. Preferably, the light unit modules include electrical circuits to provide protection against unwanted electrical noise and transients, and fail-safe circuits to revert a failed light unit module to a marker-only mode and to allow electrical communication to pass through to an adjacent light unit module.
